“For this reason God gave them up to vile passions. For even their women exchanged the natural use for what is against nature.  Likewise also the men, leaving the natural use of the woman, burned in their lust for one another, men with men committing what is shameful, and receiving in themselves the penalty of their error which was due.” Romans 1:26-27

Same sex relationships are considered to be a vile passion.

Leviticus 18:22 says, “Do not practice homosexuality, having sex with another man as with a woman. It is a detestable sin.” (NLT)

“Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God.” 1 Corinthians 6:9-11
